If you skip over the trial (or other checks) portion, you can't be sure they aren't citizens. That's part of the point. That why you extend rights to everyone, so a political party can't use the excuse of "oh, it's ok, they weren't citizens". Otherwise, it's it's a group of people collecting un-named people, deporting them, and them saying "trust us, we got it right".
